AF is equivilent to AC but assuming 100% quality. This is AF70 but 89 quality so would actually make it AF (AC) 55. There is a good conversion chart to AF to actual considering quality on Camelot Realm (http://daoc.crgaming.com/)
How rare is this drop? Been trying to find one from the Mermen in Cullen for awhile. Is this still dropped.. are the Slinkers still in the game??
